RMKS/1. This NAVADMIN addresses the Navys discontinued use of the Digital
Nautical Chart (DNC), the submarine specific product MATT, and Tactical Ocean
Data (TOD) by fiscal year (FY) 2025 and its transition to the Electronic
Navigational Chart (ENC) (using the IHO S-57 data format standard), Submarine
ENC, and Additional Military Layers (AML). The adoption of ENC enables the
ability to create and display AMLs which overlay additional information on
the navigation chart that is not available on paper or DNC.
2. With this transition, AML will replace TOD 0, TOD 4, and anti-submarine
warfare (ASW) bathymetry products. NGA will release limited coverage of ENC,
SMENC, and AML in FY20 and complete global coverage by FY24.
3. Ships equipped with ENC-approved Electronic Chart Display and Information
System (ECDIS) software shall use ENC where and when available, and continue
to use DNC where and when ENC is not available. Navy programs relying on DNC
for navigational or non-navigational purposes shall plan for DNC termination
4. The AML data layer requirements are currently being generated and will
include (not all-inclusive) contour line bathymetry; environment, seabed and
beach; large bottom objects; maritime foundation and facilities; routes,
areas, and limits; and small bottom objects. Commands should submit
additional requirements for any other desired information and unmet data
display needs as AML requirements to their Type Commander.
5. Released by VADM Jeffrey E. Trussler, Deputy Chief of Naval Operations
for Information Warfare, OPNAV N2N6.//
